High Temperature Adhesive

[Gold]

I am making some XLR patchbays that will be the central distribution point for a lot of cabling. I would like to use headers mounted on veroboard as posts to solder multiple wires to. This way I can run multiple cables where I need them to go. The problem I see is that I don't want the headers to come loose when soldering/desoldering. I would like to glue them onto the veroboard. Is there an adhesive that can take about 800ºF that would work?

There are some very high temperature adhesives use in loudspeaker internals (voice coil). Perhaps check with 3m? or Loctite?

I don't know if that would be strong enough and I don't know the correct english expression,I use high temperature silikone for high temperature stuff, normally intended for ovens / chimneys.

The highest temperature glues in voice coils are epoxies.  In Europe, Araldite is widely available and is usually CIBA's finest general purpose epoxy.  Use the normal setting stuff rather than 5min.  May be marginal as the best epoxies are only about 200C.

There are hard setting "cements" meant for exhaust repairs from car accessory shops which may be better.

You may want to solder the headers to something on the back of the Veroboard to make them less likely to fall out.  There are headers which are a snap fit into PCBs too.

JB Weld.
It'll seal a cracked radiator.

If they will stand up to soldering that sounds like the best solution. Maybe just gluing the plastic part of the header to the PCB would be close enough.

Any suggestions on a way to solder 3 or 4 wires to a single point are also welcome. I like the idea of soldering to a post because it's easy to add remove wires fairly neatly. I suppose I could also use brass nails (brads) pounded through plastic or wood.

Original Veroboard came with Veropins which locked onto the board and stood up about 10mm.

Another solution is to stretch lengths of tinned Cu wire along the Veroboard & solder to them instead.  After all, you're really just after a good way to terminate several wires.

That's a good idea. I think I even have some of that around somewhere.

Check out the swage fit pins.  I know keystone makes some:

You use a punch to flare out the non-pin end to hold it into the board.

Those look nice and like the proper thing to use. The smallest diameter pin has a mounting hole diameter of 0.047. All the prototype boards in the Mouser catalog have 0.042 hole size. I guess I could drill them out but are there mounting boards for these pins? I don't relish drilling out 300-400 holes. It would be even better if I could use the larger diameter pins.

I wonder if you could just solder to a surplus telco punch block.

If you are using a punchblock what about a punch-tool instead of soldering.

I thought about punch blocks but I want the option of connecting up to six wires per contact (said 3 or 4 before but I'd like more). I'm also using a mixture of cable. Some Mogami but mostly Belden Mediatwist 22ga solid core. I don't think ADC or 66 punch block can do that. I also thought about soldering to one but had bad memories of MCI consoles and cursing at the idiot who soldered to the punch block. I want something a little nicer.

I think I'll just bite the bullet and get a machine shop to make me some mounting boards for the swage pins. The machine shop I know works with nylon a lot. Would that work? I don't think he works with PCB material or phenolic.
